Well, after testing your scripts (and modifying the one Boyd posted), still mkpkguse.sh got exactly what I needed, in fact, I just redirected its output to package.use, because it was clean and right (I double checked).
Thanks to everyone who helped me, and specially Richard for this cool script (one of those things you archive just in case, you know). -- Daniel da Veiga Computer Operator - RS - Brazil -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GCM/IT/P/O d-? s:- a?
